In a previous post we saw a simple CAN library to handle the CAN interfaces of STM32 board. However one basic issue that we had to solve is the frames buffering (especially when we receive the frames). This issue came up by the processing time that each frame needs and the limitation that the receive interrupt routine should be as fast as possible. For that reason, the following source code presents an incoming CAN Frames software buffer, as well as a simple example using this API combined with CANBus API.

For example.
